Ala-Ala is a good test substrate [3]. Inhibited by captopril, as is peptidyl-dipeptidase A. Formerly EC 3.4.15.3, and included in EC 3.4.15.1, peptidyl-dipeptidase A.
Reaction: Hydrolysis of unblocked, C-terminal dipeptides from oligopeptides, with broad specificity. Does not hydrolyse bonds in which P1' is Pro, or both P1 and P1' are Gly
Other names: dipeptidyl carboxypeptidase (Dcp); dipeptidyl carboxypeptidase
Comments: Known from Escherichia coli and Salmonella typhimurium. A zinc metallopeptidase In peptidase family M3 (thimet oligopeptidase family). Ac-AlaAla-Ala is a good test substrate [3]. Inhibited by captopril, as is peptidyl-dipeptidase A. Formerly EC 3.4.15.3, and included in EC 3.4.15.1, peptidyl-dipeptidase A.
